The invention provides a GEO satellite disturbance torque acquisition method based on in-orbit telemetry data. The method comprises the following specific steps that: an initial moment and a time steplength are set; from the initial moment, reaction wheel rotating speed on-orbit telemetering corresponding to two moments spaced by the time step length is obtained, whether the reaction wheel rotating speed on-orbit telemetering meets a set condition or not is judged; if the reaction wheel rotating speed on-orbit telemetering meets the set condition, an interference torque M is calculated according to the reaction wheel rotating speed on-orbit telemetering corresponding to the two moments; and all interference torques M meeting the set condition are calculated, and an annual GEO satellite actual interference torque array is obtained. Therefore, technical support is provided for the improvement and optimization of a satellite attitude control scheme and satellite on-orbit accurate management.
本发明提供一种基于在轨遥测数据的GEO卫星干扰力矩获取方法,具体过程为:设定初始时刻和时间步长;从初始时刻开始,获取相隔所述时间步长的两个时刻对应的反作用轮转速在轨遥测,并判断其是否满足设定条件,若是,则根据所述两个时刻对应的反作用轮转速在轨遥测,计算干扰力矩M;计算所有满足设定条件的干扰力矩M,获得全年GEO卫星实际干扰力矩数组,为卫星姿态控制方案改进优化、卫星在轨精准管理提供技术支持。
